Sherlock Holmes is finally free to the American public in 2023.

The long-running contested copyright dispute over Sir Arthur Conan Doyle’s tales of a whip-smart detective will finally come to an end as the 1927 copyrights expiring January 1 include Conan Doyle’s last Sherlock Holmes work.

Alongside the short-story collection The Case-Book of Sherlock Holmes, books such as Virginia Woolf’s To The Lighthouse, Ernest Hemingway’s Men Without Women, William Faulkner’s Mosquitoes and Agatha Christie’s The Big Four — an Hercule Poirot mystery — will become public domain as the calendar turns to 2023.

Once a work enters the public domain it can legally be shared, performed, reused, repurposed or sampled without permission or cost. The works from 1927 were originally supposed to be copyrighted for 75 years, but the 1998 Copyright Term Extension Act delayed opening them up for an additional 20 years.

While many prominent works on the list used those extra two decades to earn their copyright holders good money, a Duke University expert says the copyright protections also applied to “all of the works whose commercial viability had long subsided.”

“For the vast majority — probably 99% — of works from 1927, no copyright holder financially benefited from continued copyright. Yet they remained off limits, for no good reason,” Jennifer Jenkins, director of Duke’s Center for the Study of the Public Domain, wrote in a blog post heralding “Public Domain Day 2023.”

That long U.S. copyright period meant many works that would now become available have long since been lost, because they were not profitable to maintain by the legal owners but couldn’t be used by others. On the Duke list are such “lost” films as Victor Fleming’s “The Way of All Flesh” and Tod Browning’s “London After Midnight.”

1927 portended the silent film era’s end with the release of the first “talkie” — a film with dialogue in it. That was “The Jazz Singer,” the historic first feature-length film with synchronized dialogue also notorious for Al Jolson’s blackface performance.

"Wings," a silent film from 1927, was the first film to win the Academy Award for Best Picture (then called Outstanding Picture).

In addition to the Alan Crosland-directed film, other movies including “Wings” — directed by William A. Wellman and the “outstanding production” winner at the very first Oscars — and Fritz Lang’s seminal science-fiction classic “Metropolis” will enter the public domain.

Musical compositions — the music and lyrics found on sheet music, not the sound recordings — on the list include hits from Broadway musicals including “Funny Face” and jazz standards from the likes of legends such as Louis Armstrong and Duke Ellington, in addition to Irving Berlin’s “Puttin’ on the Ritz” and “(I Scream You Scream, We All Scream for) Ice Cream” by Howard Johnson, Billy Moll and Robert A. King.

Duke’s Center for the Public Domain highlighted notable books, movies and musical compositions entering the public domain — just a fraction of the thousands due to be unleashed in 2023.
